To all 'whom t may concern:

Be it known that I, GEORGE J. RYMAL, a citizen of the United States, anda resident of the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Combined Kitchen- Stovesand Hot-Water Heaters, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich the invention appertains to make and use the same.

My invention relates to improvements in combined kitchen stoves and hotwater heaters.

The object of the invention is to provide a stove in which the same heatemployed for cooking purposes may be utilized for heating watersimultaneously with the process of cooking, and vice versa, therebyeffecting an economy in the consumption of fuel.

Another object of the invention is to provide a stove of this class, theparticular construction and arrangement of which, conserves the heat andaccomplishes a maximum degree of influence for any single or combinedpurpose desired. Another object of the invention resides in theparticular construction of a stove by reason of which it is possible toembody as a part thereof a water heating unit without bringing about thedisadvantage of rendering the stove impractical, or inefficient for anyone separate use intended, or to which the same may be put.

Another object of the invention is to provide a construction whichembodies such coincident relation between all the elements thereof as toaccomplish a maximum degree of eiciency, both in the consumption of fuelandin the conservation and application of heat, of a degree at leastequal to that accomplished by a stove employed for any single purpose.

Another object of the invention is to provide means whereby the stovemay be employed solelv for cooking purposes and to eliminate theperformance of the simultaneous function of heating water.

With these and other particular objects in view, all of which can not bespecifically alleged without unnecessarily encumbering thisspecification, the invention will be now described with reference to theaccompanying drawings, which form a part hereof.

n these drawings, Figure 1 is a front ele@ vation view of the stove;Fig. 2 is. a cross single purpose of cooking; and Fig. 7 is an elevationview, showing the manner of addlng other sections to the stove when arela- -tively large volume of water is to be heated.

Corresponding and like parts are referred to in the followingdescription and indicated in allv the views of the accompanying drawingsby the same reference characters.

Let the No. 5 designate the fire box portion ofthe stove in itsentirety. In this fire box portion is arranged a water circulating unit6, which forms the vertical walls of the re box portion of the stove,the same resting at its lower edge upon the fuel gratv ing 7. Oneextremity of this water circulating unit 6, is provided with a cut-outportion 8, leaving an opening into the combustion chamber 9, formed bythe water circulating unit 6. This opening registers with a fuel feedopening 10 in the ire box portion 5, said opening 10 being provided witha door 12. By this arrangement, the fuel may be fed through the opening10'and the vregistering opening 8 ofthe water circulating unit 6, intothe combustion chamber 9 of the stove. The walls of the watercirculating unit 6 are hollow, as shown at 13, and are in communicationwith induction and eductionpipes 14 and 15 respectively, which saidpipes 14 and 15 lead to radiators, or other suitable heat dispensingmeans. A transverse hollow partition 16 connects the opposite side wallsof the water circulating unit 6, establishing communication between saidside wallsl intermediate the extremities of the latter. Anotherpartition 17 extends at right angles to the partition 16 and connectsthe latter intermediate its extremities, with one end of the watervcirculating unit 6, said partition establishing` communication betweenthe hollow partition 16 and the body of they circulating unit 6. Thesepartitions 16 and 17 are spaced from the bottom of the combustionlchamber 9, permitting of,

room below said partitions for the combustion of fuel. The fire boxportion 5 o f the stove is provided with a cover 18, whlch 1s spacedabove the upper edge of the water circulating unit 6, leaving a space19, which said space 19 is in communication with a chamber 20, saidchamber 20 being formed by a laterally extended and horizontallydisposed portion 21 of the fire box 5 and cover 1S.

A baking oven 22, having compartments 23 and 24 therein, is supportedabove the fire box portion 5 of the stove, said baking oven 22 beinigsupplied with the necessary heat from the combustion chamber 9 through acontinuous heat circulating passage. The chamber 23 is entirelysurrounded by a jacket 25, which forms a passage 26 around the chamber23. A partition 27 is positioned in this passage 26, which serves todirect the smoke into a flue 28 after the smoke has iirst made acomplete traverse of the passage 26, the said flue 28 being providedwith an opening 29 therein, which is in communication with said `passage26 adjacent said partition 27. A flue 30 leads from the space 19 to thepassage 26 and communicates with the latter on one side of the partition27, which partition directs the heat units, as well as the smoke throughthe passage 26 in the direction indicated by the arrows. The chamber 24is subjected to the influence of less heat than the chamber 23, andtherefore may be termed a warming oven. This chamber 24 is formed by apartition 31 set in one corner of the jacket 25, the jacket 25 forming aportion of the wall of the chamber 24. A spa-ce 32 is left below thechamber 24, which is in communication with the {iue 80. These chambers23 and 24 are adapted to be closed by doors 83 and 34 respectively7which said doors are of ordinary form.

In warm weather, when it is unnecessary to employ the stove for househeating, less fuel will be required, and therefore, the size of thecombustion chamber may be greatly reduced. To accomplish this, I providea grate 35, which is provided with arms 36 that engage with the upperedge of the heating unit 6, whereby the grate 35 is suspended from saidheating unit 6 in one end of the latter within the space partitioned offby the partition 16, the partition 16 and the walls of the heating unit6 forming the walls of the reduced combustion chamber.

A suitable ash drawer 37 is positioned under the grate 7 within the firebox portion 5 of the stove, which drawer may be removed whenever desiredfor emptying the ashes.

By reason of the particular construction and relation of the variouselements between the fire .box portion 5 and the baking oven 22, a.direct, positive and efficient draft is created and it is made possibleto place the said baking oven above the fire boX portion 22, which isthe only convenient place the same could be put in a stove of this kind,as the entire area of the fire box portion 5 is taken up with theaccommodation of the water heating elements.

In use, water is very rapidly heated in the water heating unit 6,causing the same to circulate freely therein and to pass out through the-pipe 15 to the radiators, or other heat dispensing units.

In Fig. 7, the manner of attaching one or more stove units is shown. Inthis View, 39 represents the additional unit. rlhe same is positionedbeside the other unit and the unit 39 communicates with the other unitthrough an opening 40, which communicates with the chamber 20, a sleeve41 surrounding this opening 40-and adapted to be received into the space19 of the unit 39.

Having thus described my invention, what I claim and desire to secure byLetters Patent is l. The combination of the fire-box and grate of astove, of a hollow water circulating unit forming the vertical walls ofthe fire-box, said hollow water circulating unit resting upon the grateof the fire-box, the opposite side walls of the Nvater circulating unitbeing connected by a. transverse hollow member spaced above the grate ofthe fireboX and forming a relatively small compartment between saidtransverse hollow member and the forward end of the water circulatingunit, and `a relatively small auxiliary grate adapted to be supportedbetween said transverse connecting hollow member and said forward endmember of the water circulating unit.

2. The combination of the fire-box, and a grate of a stove, of a hollowwater circulatinig unit formingthe vertical walls of the ture.
